Lets say you live in a world where the world government has decided people are getting too addicted to the internet and ordered the internet to be shut down for 5 years. The 100 GB of storage is all you have (excluding essential system files for your Operating System). You have 24 hours before the internet is getting shut down. What do you download?
you have 100GB available. if you pack it full, you cannot unpack
What about dynamic in (system) memory decompression though?
